Title: Permanent metallic bonding method
Inventor: BACON DONALD DINGLEY
IPC: H01S5/02218
Filed: 1993-06-23
Granted: 1999-11-30
Abstract: A laser device is bonded to a diamond submount by means of a procedure including (1) codepositing an auxiliary layer, on a layer of barrier metal that has been deposited overlying the submount, followed by (2) depositing a wetting layer on the auxiliary layer, and (3) by depositing a solder layer comprising alternating metallic layers, preferably of gold and tin sufficient to form an overall tin-rich gold-tin eutectic composition. The barrier metal is typically W, Mo, Cr, or Ru. Prior to bonding, a conventional metallization such as Ti-Pt-Au (three layers) is deposited on the laser device's bottom ohmic contact, typically comprising Ge. Then, during bonding, the solder layer is brought into physical contact with the laser device's metallization under enough heat and pressure, followed by cooling, to form a permanent joint between them. The thickness of the solder layer is advantageously less than approximately 5 µm. The wetting layer is preferably the intermetallic compound Ni3, and the auxiliary layer is formed by codepositing the metallic components of this intermetallic together with the barrier metal.

Abstract: A fishing net is suspended from a corkline. A monofilament line is formed into three loops which are clamped together. The first of these three loops forms a knot around the corkline and the other two loops weave through the fishing net to hold it in place. The first loop is wound around the corkline in one angular direction for about one turn. It then crosses the portion of the first loop that is below the corkline. It then again passes around the corkline but in an angular direction opposite said one direction. Afterward, a limited portion of the loop that was rapped around the corkline is free. The other loops are then passed through this free limited portion and the knot is tightened.

Abstract: During the enzymatic "stone washing" of a denim fabric and/or garments, an undesirable redeposition of blue dye often occurs on the surfaces of the denim. The invention relates to a means of overcoming this problem using an enzyme composition comprised of Trichoderma endoglucanases and Trichoderma cellobiohydrolases that has been partially digested by a protease enzyme to separate its core and binding domains. The use of this composition reduces the redeposition of the blue dye and hence improves the stone washing process relative to using a redepositing or backstaining cellulase.
